UNITED STATES JOHN P. GRAMER, OF MUNGIE, INDIANA.

CONTAINER-CLOSURE DEVICE.

Application filed February 4, 1924.

To all whom it may concern Be it known that 1, JOHN P. Gunmen, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Container-Closure Devices, of which the following is a specification.

This invention relates to improvements in containers of that type comprising bottles, jars and the like having closure means by which the mouth or opening of the container is covered and sealed.

The object of my invention is to provide a container having its mouth rim of such form, and a cap element of such construction, combination and arrangement with the said mouth rim,that while the said cap may be easily applied and secured at position against accidental dislocation or displacement, it is at the same time, capable of being easily loosened and removed, without the use of a tool or implement.

The above general objects, and also the more specific purposes of my invention, are accomplished by the new construction, com bination and arrangement of parts described in the following specification, and illustrated in the accompanying drawings.

The invention is defined in the appended claims. Suitable characters of reference are applied to the diiferent parts of the invention as they appear in the different views, in the. drawings, in which Figure 1 is a side View of the upper portion of a bottle showing the peculiar form of mouth rim, with which the cap is combined.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a side View of the container closure-device complete, the cap being at initial applied position but at drawn or secured engagement.

Figure at is a plan view of Figure 3.

Figure 5 shows the container in the same. position as in the previous views, but with the cap turned to the position where it has become secured.-

Figure 6 is a plan view of Figure 5.

Figure 7 is a bottom plan view of the cap.

Figure 8 is an enlarged side view of the cap, as it appears at Figure 5.

Figure 9 is an enlarged vertical sectional view taken on the line 9-9 in Figure 6.

view taken on the line 1111 in Figure 4.

The invention contemplates the providing of an annular external rim at the mouth of the container, with spaced angular recesses, and a one-piece metal cap having a periph eral wall to enclose said rim and provided with angular inturned lips, the points of said lips being slightly raised and the bases of said lips being adapted to engage the outer lower edges of said recesses, and a catch on the wall of the cap and located between the lips, adapted to normally press against the rim, but which upon rotative shifting of the cap becomes engaged with one of the recesses.

In a container of the type shown, namely a bottle 1, a rim 2 of the form in cross section as shown, is provided with three angular recesses 3 spaced apart as shown.

Adapted to rest upon the said mouth rim 2 is a circular cap lmade of sheet metal and having vertical wall to freely engage the said rim.

Formed integral with the bottom edges of the cap wall are inturned lips 5 spaced in conformity with the spacing of the recesscs 3.

At a location between two of said lips is provided an integrally formed catch 6 whose function is to bear against the mouth rim and to become engaged with one of the recesses, when the cap will have been moved rotatively as will be hereinafter described. The form of the catch 6, is plainly shown in Figures 8 and 10, in which is seen the outwardly disposed end 6*, and which passes the surface of the mouth rim when the cap is lowered thereon, the body portion of which resilient catch has bearing against the vertical face of said rim.

The form of each of the aforesaid lips 5 is shown in detail in Figures 7 and 9. In plan the dimensions and angular shape of said lip are such that the lip freely passes the recess 3 when the cap is lowered to the position on the mouth rim. The point 5 of the lip is slightly higher than the base portion of the lip, and by which is thus formed the sloping edges 5. By this construction and arrangement it is apparent that when the cap is moved rotatively the sloping edge 5* of the lip causes the cap to be drawn downwardly; the underside thereof being drawn into close contact with the top of the mouth rim. This function is performed by each of the lips regardless of the. direction in which the caps may be turned. When the cap will have been moved or turned to the position above described, the catch 6 will have been brought to registration with one of the recesses 23 and into which it re tracts or snaps and which then occupies the position as shown in Figure 10. The cap in this position, is secure against accidental slippage or movement rotatively and all possibility of the container being prematurely or accidentally opened is prevented. At the same time while the cap is retained in sealed engagement, it is capable of being loosened and easily removed without the use of an implement or tool.

To remove the cap, it is simply moved or turned rotatively in either direction, the catch (3 l eing pressed outwardly by the sloping wall of the recess 3 whence the said catch again occupies the position shown in Figure 11, and the lips will have been returned to registration with the recesses The cap may then be lifted free from the container.

Advantages are that a mouth rim of the form shown is easily capable of economical manufacture in glass or any f the cast or plastic substances used for container construction. The metal cap of one piece construction is extremely economical of manufacture. The placing of the cap in position and the. nature of the movement imparted to same to cause it to become secured or locked, is so simple and apparent, that the invention is not only economical of manufacture, but is simple, easy and practicable to use.

here a hermetic sealing of the container is desired, there may be used a packing or inner-liner, which may be made of cork, rubber, or any other suitable material,

By my invention there is retained the advantage of a rimmed opening so desirable in containers in which liquids are retained. In most all devices involving removable caps and wherein the container neck or mouth is provided with interrupted threads or lugs, there is necessarily absent the annular like rim which is very essential for the easy pouring of the contents. lVhile in my in vention there are recesses provided in the annular rim, there are segmental portions of the rim of such extent, not affected by the recesses that my container retains all of the advantages of the bottle having the standard type of annular rim. In my invention the container has a rim, and the cap has the lock. .Vhile in this specification I have shown my invention embodied in a bottle type of container, and the rim having three recesses provided therein, it will be understood that the invention is applicable to use in containers of different kinds, such as or jugs, and the like. Also, minor changes may be made in the form and specific fea- 1,5aa91o tures of the invention, within the scope of same as defined in the appended claims, without departing from the spirit of the invention or sacrificing any of its advantages.

hat I claim as my invention, and desire to secure by Letters Patent, is 2* 1. In combination with a container having an annular mouth-rim provided with spaced external angular recesses, of a metal cap having a vertical peripheral wall to surround said rim and provided with angular inturned lips the points of said lips being slightly raised and the bases of said lips being adapted to engage the outer lower edges of said recesses, and a catch on the cap and located between the said lips, adapted to normally press against the rim but which upon rotative shift of the cap becomes engaged with one of the recesses.

2. In combination with a container having a mouth-rim provided with external vertical angular recesses, of a cap having inturned lips of angular form to register with the said angular recesses, the point of each lip being slightly raised and the bases of said lips being adapted to engage the outer lower edges of said recesses so that upon rotative shift of the cap it becomes tightened on the said rim.

3. A closure cap for externally recessed mouth rim, consistin of a body piece having its peripheral wall of depth equal to that of the rim and being provided with centrally pointed inturned lips the points of which are slightly raised, a resilient tongue in the wall adapted to press against the mouth rim when the cap is lowered thereon, and to engage one of the recesses when the cap is shifted rotatively.

t. A cap, for externally recessed mouth rims consisting of a circular flat body piece adapted to cover the mouth rim, a vertical peripheral resilient wall for the body piece, having a plurality of integrally formed centrally pointed inturned lips the points of which are raised, and an inwardly disposed resilient tongue formed integral with the.

said wall, and being adapted to engage the vertical external face of the mouth rim when lowered, and to engage one of the mouth rim recesses when the cap is shifted rotatively.

5. In combination with a container ha"- ing a mouth rim provided with external vertical angular recesses, of a cap having inturned lips of angular form to register with said angular recesses, said lips having such angle of inclination relative to that of the lower face of the said mouth rim, that upon rotative shift of the cap it becomes tightened on the rim. 7
